When on the small rear cog, the derailleur should be at its forward-most position with just minimal take-up by the jockey wheels.
thanks, mike. the derailleur shifts fine into the largest cog, so i don't think the chain is too short, but maybe i should look into it. this is my first simplex derailleur i've worked with, and it's different from the newer slant parallelogram mechs i've worked with. my method for determining the chain length is to wrap the chain around the largest cog with the derailleur stretched to capacity. then overlap with two links. should i be doing something else?
